Why Is American Healthcare So Expensive?
The United States spends about $15,000 per person a year on healthcare — roughly twice what other wealthy nations pay — and finishes near the bottom of the G7 on life expectancy. The evidence points to one answer more than any other: not that Americans use more care, but that each unit of care costs more.
It's the prices, not the usage
A natural first guess is that Americans are simply sicker, older, or more frequent users of the healthcare system than people in other wealthy countries. The data doesn't support that. On most standard measures — doctor visits per person, hospital admissions, average length of stay — the U.S. is in the middle of the pack among peer nations, sometimes below it. What's different is the price tag attached to each visit, each prescription, and each hospital day.
Prescription drugs: the clearest example
The same drug, from the same manufacturer, routinely costs several times more in the United States than it does across the border. A 2020 GAO audit found the VA — which negotiates directly as a single national buyer — paid roughly 54% less than Medicare for 399 matched drugs, because federal law gives the VA negotiating leverage it denies Medicare. Three pharmacy benefit managers control roughly 8 in 10 U.S. prescriptions, each owned by the same corporate family as a major insurer.

Insurance overhead that adds no clinical value
A large share of every healthcare dollar in the U.S. goes not to care but to the machinery of billing, coding, prior authorization, and claim disputes between providers and insurers. The U.S. spends roughly $1,055 per person on insurance and billing administration — compared with about $245 in comparable countries. Denials add another layer: 82% of Medicare Advantage prior-authorization denials are overturned when a patient actually appeals, meaning most denials were never medically justified in the first place — just a delay, and a deterrent.

Consolidation and private equity
Hospitals, physician practices, and insurers have consolidated sharply over the past two decades, and the evidence on what that consolidation does to price is consistent: it goes up. A 2023 JAMA study found hospital-acquired conditions rose about 25% after private equity acquired a hospital. A broader systematic review of private-equity ownership across healthcare settings found cost increases in nine of twelve studies examined, and decreases in none.
What the evidence shows, and what it doesn't
None of this means every dollar spent on American healthcare is waste, or that every participant in the system is acting in bad faith. Some of the price difference reflects genuine investment — in research, in newer facilities, in being first to market with new treatments. But the specific, measurable gaps above — in drug pricing, in administrative overhead, in what happens to prices after consolidation — are large enough, and consistent enough across independent studies, to account for most of the difference between what America pays and what its peers do. The honest version of the story is a system where prices, not sickness or overuse, do most of the explaining.
